Introducing Smileball, the World’s First Smile Controlled Pinball Machine from KPT, a Swiss health insurer who claims to have Switzerland’s happiest health insurance clients, so they created Smileball to show that less anger equals more smiles.

It’s pretty simple, a camera captures the player’s face and from there, face-tracking software transmits the mouth movements to an Arduino Board which is connected to the servos that power the flippers on the pinball machine. They’ve also created a version you can play online.You can check it out here to play. (thanks Daniel)
